Urban environmental sanitation is getting worse and worse, walking on the street can always see littering: the road was thrown to the roadside mineral water bottles, the library was thrown everywhere in the draft paper, the sidewalk littering cigarette butts, trampled chewing gum ...... All to the sanitation workers increased a lot of work. If none of this had happened, everyone would have held out a player, and the finished mineral water bottle and the used draft paper would have been thrown into the trash can, and the cigarette butts would have been thrown into the cigarette butts recycling area of the trash can ...... Would the social environment be different.
